“He was really into computers. That's what he loved to do,” Greim added.

When the Navy destroyer collided with a merchant ship, 31-year-old Findley was aboard the vessel off the waters of Singapore.

As of Tuesday, Navy officials confirmed five sailors were hurt and 10 others are missing.

“It's crazy how much he excelled. He's always graduated first of his class. He became First Class. He's getting awards; he's sailing around the world; he fell in love with a woman named Riho and married her,” Greim said.

Tuesday, Navy officials began identifying some sailors' remains, but Greim said they aren't getting any other information.

“All we're waiting for is answers, and no one is giving us any information,” Greim said. “I want to know where my brother is. I want to know what's taking so long.”

Findley has an 8-year-old daughter and a six-year-old son who live in Virginia with their mom.

“We still don't know where my brother is and also the other men that are with my brother, they're missing too. And families are wondering, where are their loved ones?” Greim said. “I probably have lost my little brother, and now we're on day three, day four, and he could have been electrocuted. He could have drowned. I don't know what's happening.”

A Navy spokesman would only say as of Tuesday night, Petty Officer First Class Findley's "whereabouts remain unknown."
